Printrbot Part 3 : Bowden Setup

I totally forgot to write about my bowden setup. I will keep this brief, because it is very simple. Below are pictures of the parts with comments.Above is the bowden coupler. I parameterized it better and simplified the script over the original. The new script allows me to take into account offsets in the hole and …

Printrbot Part 2

I have been taking my time putting it together, slowly assembling. I think in my old age(18) I've started becomeing more meticulous :p. Anyway, I am pretty much completed with the build. Over all goal were met. It is transportable, and very light. It should serve as a good hacking platform. It is going to …

Deltafab Part 1 of many

Deltafab has been a kind of dream project for me. I've always been fascinated by the speed of delta robots.  In June of this year I had first started pondering how would be the best way to go about making a mostly reprappable delta robot. I eventually thought about breaking up the pivots into two locations. I …

Printrbot Part 1

I spent most of the first third of my Winter break off from University hacking on the printrbot design posted by whosawhatsis. I wanted to make a few optimizations and most importantly separate the parameterizations of the smooth and threaded rod. Unfortunately, I altered a bit too much in the script to merge easily. Lesson learned, make small alterations …

New vertexes

I couldn't help myself. As mush as I liked Whosawhatsis' vertexes, i felt they could be optimized. I think I just hate squares and like putting circles around my circles. Why? Because when i write the openscad script, i just put it in a union and increase the radius. I might be confusing optimization with …

Mixtape Mendel Updates

More likely back to the mixtape mendel project. I have had, in my head, the ideas I want to implement into version 0.2. Many of these things are fundamentally sound. I also wanted to test out some of the hardware and software I would be using on testing mixtape mendel. Partially to eliminate variables. Most …

Version 0.1 to 0.2

Here is what I have learned from version 0.1.- Tapping plastic works well.- I need to make my parts a tad bit thicker.- In OpenSCAD, I should never use scaling factors to describe walls, but rather hard millimeter values.- Having a configuration file would be awesome.- I should flip the smooth and threaded rods on …

2cm of Z travel and other updates

I figure I will just post up some pics. It turns out I need to rework the top piece and bottom piece, because the motor hits the side rods on the triangle. This effectively makes my x travel around 2cm. 6cm if I pretend the print bed is non existent. I am going to flip …

Why this week hasn’t had any developments

http://www.thingiverse.com/thing:6067I have been preparing for my Science Olympiad competition the past week. I already have a road map for next week, and have started thinking about version 0.2 for mixtape Mendel. All I can say is expect alot next week. My smooth rod will be here possibly, and I will be printing and designing version …

The top piece, mistake turned experiment, and looking like a printer

Yes, lots to blog about about. First, the top piece. I got most of my ideas from hacklab.to for this part. Most of it isn't interesting, except for an accident in the design I made. I had originally intended to shift the motors outward to allow for room for the nuts. As I was finalizing …
